The object of this invention is to furnish improved lockets made ofstone, jemand other materials, but especially of stone, which shall beso constructed that no metal will be visible except the loop or eye toreceive the guard, and which shall be simple in construction, neat andbeautiful in appearance, and not liable to get out of order.

The invention consists in the combination of the hinged dovetailedstrips of metal with the eye or loop, the central ring, and the groovedinner surfaces ofthe side plates, as hereinafter fully described.

A are the side plates of the locket, which are made of concavo-convexform, and may be oval, circular, or of other shape, as may be desired.The edges of the side plates A shut down against and t upon the sideedges of a central ring, B. The inner surfaces of the plates'A havedovetailed grooves formed in them to receive the dovetailed strips ofmetal to Which the central ring B is attached by a pin or rivet. To thefree ends ofthe metal strips C are attach ed catchesE, to enter a notchin the inner surface of the central ring B, and catch upon a piece ofmetal, F, placed in a groove in the said inner surface of the saidcentral ring B.

With this construction the locket, when closed, Will present a smoothsurface of stone, except the eye or loop D, to which the guard isattached, and at the same time the locket Will be firm and strong, andnot liable to get out of order.

Having thus fully described my invention, I claim asneW and desire tosecure by Letters Patent- The combination of the hinged dovetailedstrips of metalC With the eye or loop D, the central ring B, and thegrooved inner surfaces of the side plates A A, substantially as hereinshown and described.
